As a college student I'd like to get something out. This is some real talk regarding college students (not all my friends or others on my campus, but some) who use sex as a status symbol or method of control.
Ladies, you don't exist solely to be sex toys, maids, or eye candy. You're human. Stop taking your freedoms for granted and find something that defines you besides partying, Thirsty Thursday, or opening your legs and mouth for every frat hunk. If your man is hurting you, leave him and seek help. Did Susan B. Anthony march on the streets only for you to be a suckup to an oppressive patriarchy? Think about it. The women's rights activists of the 19th and 20th centuries roll in their graves for every woman who perceives herself as a mere slave to her boyfriend/husband. Just like how Martin Luther King, Jr. would be disgusted if he could listen to any modern rap musician (like Waka Flocka Flame).
Gentlemen, if you've slept with the entire cheerleading squad and have given blowjobs to every bleached blonde sorority chick with breast implants but have yet to find a working job or (if you're in college for 2 years or more) a meaningful internship, then you're just plain worthless. You ain't that strong if you can hook up with everyone yet have little real characteristics like intelligence or sociability. When you're in a relationship, be respectful and have basic human dignity: do not resort to violence to get your point across or to take out your anger. Your girlfriend is a human being just like you, not a punching bag or chattel.
My good friend Rishabh has this classic Tumblr quotable:
I believe girls that tie themselves up in “drama” need to feel like their life is worth something. It’s just sad that they don’t realize that filling up their days gossiping about others doesn’t make THEIR lives any better. You just come off as a shitty person. Girls who spend their days gossiping and revolve their lives around petty bullshit are not worth knowing. Also, girls who center their lives around “Thirsty Thursdays” and partying are not worth knowing either.That's right. If your life revolves around "scoring" every shallow one around you who looks cute or getting drunk and dancing in a club whose speakers are blasting out your eardrums, I don't desire to know you. F-word off.
Bottom line: while sex may be good, do not let it define who you are. Let your character define you. There's much much much much^(infinity) more to life than fooling around in bed and stimulating each other, so if your partner says "no", find something else to do.
